syslog-ng automatic reboot upon USB failure

syslog-ng.conf

# These next three lines monitor the log for indications
# that the USB device has gotten into a bad state. When we
# notice that the USB device is in a bad state, we want to
# reboot. However, in order to avoid reboot loops, we only
# allow a reboot to occur if the system has been up for
# longer than 5 minutes. -- RQ 2016-09-17
